Question

Can someone help me with these problems and explain them as well please

Answer 1

3. b=112

4. x = 60

Explanation:

3.

b is equal to 112 since 68+b will be equal to a supplementary angle; an angle that adds up to 180. 180-68 is equal to 112.

4.

35+25 = 60, therefore x = 60.

Answer 2

b=112°

Explanation:

two complementary angles

b=180°-68°=112°

sum of 2 angles is

x= 35°+25°=60°
